STEP 1

Copy chess engine to directory on your computer.

STEP 2

Click on square button with „...”

STEP 5

You will see something similar to this picture:

Find directory where you had copy RYBKA engine.

Underline and click on engine file i.e. Rybka v1.0.exe

Click open. You should see:

Click OK. You install Rybka engine inside Junior GUI.

Now, you have to only change an engine. To do it click on icon of the engine you are currently using.

On the picture below it is Junior 9

In a gray window „Load engine” which will appear you will see list of engines.

Pick the one you want to analyze chess with and click OK.

In gray window you can also choose the numbers of MB for hash tables according to the type of computer you have.

Rybka engine uses this memory (MB) to remember the positions it has searched,

so a bigger hash table will slightly increase its level.

Just make sure that your computer has enough memory for the hash tables well as any other

applications (programs) which are running (i.e. music in the background).

If you set the hash table size too high, the operating system will start using the hard drive,

which you definitely want to avoid. If you’re not sure, choose a small value.

If you choose to big number for your hash table it can slow down the engine.

Click OK. You are finally done.
